Cornell tsunami expert to lead U.S. scientific delegation into Sri Lanka’s wave-ravaged areas

05.01.2005


Philip Liu, Cornell University professor of civil and environmental engineering, will lead a delegation of American scientists from the National Science Foundation’s Tsunami Research Group and the U.S. Geological Survey (USGS) into the tsunami-ravaged areas of Sri Lanka, Jan. 9-16.



The scientists will examine inundation areas, estimate wave heights, determine the precise arrival time of the tsunami, scour the area for geological evidence and sediment deposits and examine structural damage. "The goal here is to obtain information to further our understanding of these waves, with the hope of improving predictive capabilities and help future development of tsunami warning systems," Liu wrote in a letter to Gen. Asoka Jayawardhama of Sri Lanka’s defense ministry.

Undersea earthquakes, landslides or volcanic eruptions produce these giant seismic sea waves. Liu’s prime expertise is in tsunamis and waves propagation, and he helped to develop the tsunami warning system for countries surrounding the Pacific Ocean.


His research centers on understanding the characteristics of ocean-wave climates and the way that waves interact with coastlines and coastal structures. "We are engaged in theoretical research on the propagation and transformation of linear and weakly nonlinear water waves over complex ocean bathymetry [changes in water-depth measurements]," Liu says. His Cornell team has developed a model to calculate wave amplitude and the direction of wave propagation in the near-shore environment.

At Cornell, Liu uses a 120-foot-long wave tank to research the sediment transport and ripple formation under ocean waves. Liu employs particle imaging velocimetry, which measures the speed of water turbulence under breaking waves. He is developing numerical schemes, using the Cornell Theory Center’s supercomputing facilities, to generate three-dimensional images of flows to measure the dynamics of water waves.

Joining Liu on this mission to Sri Lanka will be: Harindra Joseph Fernando, professor, Arizona State University; Costas Synolakis, professor, University of Southern California; Patrick Lynett, assistant professor, Texas A&M University; Bretwood Higman, graduate student, University of Washington; Bruce Jaffe, oceanographer, USGS; and Robert Peters, geologist, USGS. Three New Zealand scientists also will join the American team: James Goff, geologist, GeoEnvironmental Consultants; William Power, physicist; and Neville Palmer, GPS technician, both from the Institute of Geological and Nuclear Sciences.

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
